iOS: At first Snozerr looks like most audio recorders, until you notice the button for the camera. This app gives you the ability to take photos while recording audio; each picture is timestamped to the point in the recording where the photo was taken, and you can easily synchronise the images with the audio for later playback.
This combination of features makes Snozerr an ideal app for students recording lectures and workers recording presentations with lots of infographics. You can use the timestamped photos to target the interesting parts of the lecture and ignore the non-relevant parts. All of the voice and photo files created in one session are linked together, so it is easy to share content with your peers. The app also supports nested hierarchical organisation, dual cameras, and sending files by email.
The app is very easy to use and delivers on its promises. Snoozerr is $0.99 in the iTunes App Store.
